Yes and yes. If I lift the landing gear to re-seat the ball, the truck will move with or without emergency brake on - happens every time I unhitch or hitch at any site. Sometimes the truck will move forward, sometimes back. This happens in normal driving with nothing in tow every time I park. For instance backing into garage I have very little room due to the length so I try to get the truck an inch away from the wall in the back. Sometimes it will move forward and sometimes back when I put it in park and take foot off the brake and that is with the E-brake on and relatively level garage floor. Every time I put it in park, DW has to tell me - nope pull forward or back an inch as the ball isn't centered any longer to drop the coach.

Thanks Keith. The movement I see is in my rearview mirror not the side mirrors just to confirm. But good to hear that someone else has wrinkles. If it weren't for the other items, I'd be less concerned. This may all be OBE and nothing is wrong but the concern has been there since our first trip when all the filon trim screws snapped on door side and filon was flapping in the breeze. That set the tone for me to glance in rearview mirror a bit more than I would have in tow.

With the e-brake applied the truck should not move (or at least none of mine do with properly adjusted brakes). Might be worth having a friend help you by rocking the truck while you look under with the e-brake applied to see if you can figure out where the movement is coming from. The only other thing I can think to try and keep the truck from moving is to chock those wheels also. I do carry 2 sets of chocks and chock both sides of my trailer plus I have a spare set if I need them for the truck.

x2 on Jlawles2 Joseph's comment. If your truck is moving with the emergency (E) brake applied, that is something that needs to be serviced. The small movement after putting the truck in Park and releasing the main brake pedal is normal.
